A 10b5-1 plan is a pre-arranged stock trading plan that allows company insiders (officers, directors, employees with material non-public information) to buy or sell their employer's stock on a predetermined schedule without violating insider trading rules. The plan must be set up when the insider has no material non-public information (MNPI), and trades execute automatically thereafter regardless of what the insider knows.
Insider trading rules generally prohibit corporate insiders from trading on material non-public information. For executives who routinely have MNPI (about earnings, M&A activity, clinical trials, regulatory matters), this creates very narrow legitimate trading windows, usually a 30-45 day period after each quarterly earnings release, before the next quarter's data accumulates. For an executive trying to systematically diversify a concentrated position, this is impractical.
10b5-1 plans solve this problem by allowing the insider to commit to a trading schedule when they have no MNPI. The plan specifies amounts and timing in advance: 'sell 5,000 shares on the first trading day of each month at market price for the next 24 months,' or 'sell 10,000 shares each time the stock trades above $200, up to 100,000 total.' Once the plan is in place, trades execute according to the plan regardless of what the insider learns afterward.
The SEC adopted significant amendments effective February 2023 that tightened 10b5-1 requirements: a mandatory cooling-off period of 90 days (or 2 days after the next earnings release, whichever is later) before trades can begin; restrictions on overlapping plans; certifications by directors and officers that they're not aware of MNPI when adopting plans; and required disclosure of plan details in SEC filings. These rules were designed to prevent abuse by insiders setting up plans immediately before negative news.
For Northern Suburbs executives at AbbVie, Abbott, Baxter, Walgreens, Zebra, or other public companies, a 10b5-1 plan is the standard tool for systematic diversification of concentrated company stock. Plans typically run 12-24 months, sell a fixed share amount or dollar value each month or quarter, and are coordinated with the executive's broader retirement and tax plan. Companies usually require pre-approval through their general counsel's office before plans can be adopted.
Key facts
- 10b5-1 plans must be adopted when insider has no material non-public information
- SEC 2023 amendments: 90-day cooling-off period for officers/directors before first trade
- Mandatory disclosure: directors and officers must disclose plan adoption, modification, and termination in 10-Q/10-K
- Plans must be entered in good faith and operated in good faith for the entire duration
- Multiple overlapping plans by the same insider are generally restricted
- Modifications/cancellations: trigger new cooling-off period before subsequent trades
Can I cancel my 10b5-1 plan if the stock price falls?
Technically yes, but it raises serious concerns. The SEC and plaintiffs' attorneys scrutinize cancellations closely, a plan cancelled before adverse trades suggests the insider may have had MNPI when adopting the plan, undermining the affirmative defense. Cancellations also trigger new cooling-off periods before any subsequent plan can begin trading. Best practice: structure plans conservatively at adoption (price floors, share caps, time-based triggers) so cancellation isn't necessary; cancel only with written legal opinion supporting the decision.
Do directors of private companies need 10b5-1 plans?
Generally no, 10b5-1 protections apply specifically to publicly traded company stock under the Exchange Act. Private company insiders trade infrequently and through structured liquidity events (tender offers, secondary sales, IPOs, M&A) where insider trading rules apply differently. However, when a private company is preparing for IPO or a major liquidity event, insiders may want to consider trading plan structures to avoid exactly the issues that 10b5-1 plans solve in the public context.
